    SpringCloud 整合 Quartz 支持集群,支持动态修改 Quartz 执行时间

    一、添加 maven 引用包


    <dependencies>
        <!-- 访问数据库模块 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
    
        <!-- web模块 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    
        <!-- MYSQL -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
    
        <!-- Jdbc 模块 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
    
        <!-- log4j 日志模块 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j</artifactId>
        </dependency>
    
        <!-- quartz 模块 -->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>
    
        <!-- druid 线程池模块 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.3</version>
        </dependency>
    

    二、添加 3 个配置文件


       1、src\main\resources\application.yml 文件:
    
       server:
            port: 8395
       spring:
            application:
                name: microservice-simple-quartz-cluster
            datasource:
                driver-class-name: com.mysql.jdbc.Driver
                url: jdbc:mysql://ip:port/hmilyylimh?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true
                username: username
                password: username
            jpa:
                hibernate:
                    ddl-auto: update #ddl-auto:设为update表示每次都不会重新建表
                    show-sql: true
    


        2、src\main\resources\quartz.properties 文件,配置quartz:
    
        org.quartz.scheduler.instanceName = quartzScheduler  
        org.quartz.scheduler.instanceId = AUTO  
    
    
        org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX  
        org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
        org.quartz.jobStore.tablePrefix = QRTZ_  
        org.quartz.jobStore.isClustered = true  
        org.quartz.jobStore.useProperties = false
        org.quartz.jobStore.clusterCheckinInterval = 20000    
    
    
        org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool  
        org.quartz.threadPool.threadCount = 10  
        org.quartz.threadPool.threadPriority = 5  
        org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
    


        3、src\main\resources\quartz.xml 文件,配置定时任务:
    
        <?xml version="1.0" encoding="UTF-8"?>  
        <beans xmlns="http://www.springframework.org/schema/beans"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
               xmlns:p="http://www.springframework.org/schema/p"
               xmlns:aop="http://www.springframework.org/schema/aop" 
               xmlns:context="http://www.springframework.org/schema/context"
               xmlns:tx="http://www.springframework.org/schema/tx"
               xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
                        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
                        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    
    
    <bean id="testJobDetail" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- durability 表示任务完成之后是否依然保留到数据库,默认false -->
        <property name="durability" value="true" />
        <property name="requestsRecovery" value="true" />
        <property name="jobClass">
            <value>
                com.itmuch.cloud.job.DetailQuartzJobBean
            </value>
        </property>
        <property name="jobDataAsMap">
            <map>
                <entry key="targetObject" value="testScheduleTask" />
                <entry key="targetMethod" value="sayHello" />
                <!-- 是否允许任务并发执行。当值为false时,表示必须等到前一个线程处理完毕后才再启一个新的线程 -->
                <entry key="concurrent" value="false" />
            </map>
        </property>
    </bean>
    
    <bean id="testJobTrigger"
          class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="testJobDetail" />
        </property>
        <property name="cronExpression">
            <value>0/10 * * * * ?</value><!--每10秒钟执行一次 -->
        </property>
    </bean>
    
    <bean id="startQuertz" lazy-init="false" autowire="no"
          class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
          destroy-method="destroy">
        <!--QuartzScheduler 启动时更新己存在的Job,这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了 -->
        <property name="overwriteExistingJobs" value="true" />
        <property name="startupDelay" value="2" />
        <property name="autoStartup" value="true" />
        <property name="triggers">
            <list>
                <ref bean="testJobTrigger" />
            </list>
        </property>
        <property name="dataSource" ref="dataSource" />
        <property name="applicationContextSchedulerContextKey" value="applicationContext" />
        <property name="configLocation" value="classpath:quartz.properties" />
    </bean>
    
        </beans> 
    

    三、DetailQuartzJobBean 加载类和方法


    package com.itmuch.cloud.job;

    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    import org.slf4j.LoggerFactory;
    import org.springframework.context.ApplicationContext;
    import org.springframework.scheduling.quartz.QuartzJobBean;

    import java.lang.reflect.Method;
    import java.text.SimpleDateFormat;
    import java.util.Date;

    public class DetailQuartzJobBean extends QuartzJobBean {

    private String targetObject;
    private String targetMethod;
    private ApplicationContext ctx;
    
    // 配置中设定了
    // ① targetMethod: 指定需要定时执行scheduleInfoAction中的simpleJobTest()方法
    // ② concurrent:对于相同的JobDetail,当指定多个Trigger时, 很可能第一个job完成之前,
    // 第二个job就开始了。指定concurrent设为false,多个job不会并发运行,第二个job将不会在第一个job完成之前开始。
    // ③ cronExpression:0/10 * * * * ?表示每10秒执行一次,具体可参考附表。
    // ④ triggers:通过再添加其他的ref元素可在list中放置多个触发器。 scheduleInfoAction中的simpleJobTest()方法
    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        try {
            Object otargetObject = ctx.getBean(targetObject);
            Method m = null;
    
            System.out.println(targetObject + " - " + targetMethod + " - " + ((new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS")).format(new Date())));
            try {
                m = otargetObject.getClass().getMethod(targetMethod, new Class[] { JobExecutionContext.class });
                m.invoke(otargetObject, new Object[] { context });
            } catch (SecurityException e) {
                // Logger.error(e);
                System.out.println(e.getMessage());
            } catch (NoSuchMethodException e) {
                // Logger.error(e);
                System.out.println(e.getMessage());
            }
        } catch (Exception e) {
            System.out.println(e.getMessage());
            throw new JobExecutionException(e);
        }
    }
    
    public void setApplicationContext(ApplicationContext applicationContext) {
        this.ctx = applicationContext;
    }
    
    public void setTargetObject(String targetObject) {
        this.targetObject = targetObject;
    }
    
    public void setTargetMethod(String targetMethod) {
        this.targetMethod = targetMethod;
    }
    

    }


    四、调度服务接口


    package com.itmuch.cloud.service;

    import java.util.Date;

    import org.quartz.CronExpression;

    /**

     */  
    void schedule(String cronExpression);

    void schedule(CronExpression cronExpression);  
    
    /**

    }


    五、调度服务接口实现类


    package com.itmuch.cloud.service.impl;

    import java.text.ParseException;
    import java.util.Date;
    import java.util.UUID;

    import com.itmuch.cloud.service.ISchedulerService;
    import org.quartz.CronExpression;
    import org.quartz.JobDetail;
    import org.quartz.Scheduler;
    import org.quartz.SchedulerException;
    import org.quartz.TriggerKey;
    import org.quartz.impl.triggers.CronTriggerImpl;
    import org.quartz.impl.triggers.SimpleTriggerImpl;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;

    /**
    * 调度服务实现类。
    *

    *
    */
    @Service(“schedulerService”)
    public class SchedulerServiceImpl implements ISchedulerService {

    private static final String NULLSTRING = null;  
    private static final Date NULLDATE = null;  
    
    @Autowired

    }  
    
    @Override

    * sayHello 方法名称在 quartz.xml 中配置为属性 targetMethod 的 value 值。
    *
    * @date 2017/9/16
    *
    */
    @Configuration
    @Component(“testScheduleTask”)
    @EnableScheduling
    public class ScheduleTask {

    private static final Logger Logger = LoggerFactory.getLogger(ScheduleTask.class);
    
    public void sayHello(JobExecutionContext context){
        Logger.info("====    sayHello 123456789    ====");
        System.out.println("====    sayHello 123456789    ====");
    }    
    

    }

    import org.springframework.context.annotation.ImportResource;

    /**
    * 简单Quartz-Cluster微服务。

    * @date 2017/9/16
    *
    */
    @SpringBootApplication
    @ImportResource(“quartz.xml”)
    public class SimpleQuartzClusterApplication {

    private static final Logger Logger = LoggerFactory.getLogger(SimpleQuartzClusterApplication.class);
    
    public static void main(String[] args) {
        Logger.info("简单Quartz-Cluster微服务入口函数编码-" + System.getProperty("file.encoding"));
    
        SpringApplication.run(SimpleQuartzClusterApplication.class, args);
    
        System.out.println("【【【【【【 简单Quartz-Cluster微服务 】】】】】】已启动.");
    }
    

    }


    九、如何测试分布式?


    /******************************************************************************
    一、简单Quartz-Cluster微服务:

    1、添加 Quartz 相关配置文件;
    2、启动 microservice-simple-quartz-cluster 模块服务,启动1个端口(8395);
    3、然后查看日志, ScheduleTask 类的 sayHello 方法被有规律的调用,并打印日志出来;

    4、启动 microservice-simple-quartz-cluster 模块服务,再启动2个端口(8396、8397);
    5、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法,因此 Quartz 的集群分布式也算是部署成功了;
    ******************************************************************************/

    /******************************************************************************
    二、简单Quartz-Cluster微服务(动态修改定时任务的 cronExpression 时间表达式):

    1、添加 Quartz 相关配置文件;
    2、启动 microservice-simple-quartz-cluster 模块服务,启动3个端口(8395、8396、8397);
    3、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法打印了日志,因此 Quartz 的集群分布式也算是部署成功了;
    4、然后新起网页输入 http://localhost:8395/modify/5 修改定时任务的触发时间;
    5、再等一会儿就看到 3 台服务器只有 1 台服务器每隔 5 秒调用一次 sayHello 方法,因此修改定时任务的克隆表达式也算是成功了;
    ******************************************************************************/

    /******************************************************************************
    三、简单Quartz-Cluster微服务(动态删除其中 1 台活跃 Quartz 服务器,然后剩下的其中 1 台自动接替):

    1、添加 Quartz 相关配置文件;
    2、启动 microservice-simple-quartz-cluster 模块服务,启动3个端口(8395、8396、8397);
    3、然后看到 3 台服务器只有 1 台服务器调用了 sayHello 方法打印了日志,因此 Quartz 的集群分布式也算是部署成功了;
    4、然后关闭 1 台活跃 Quartz 服务器;
    5、再等一会儿就看到 2 台服务器中的 1 台服务器每隔一定的时间调用一次 sayHello 方法;
